Detailed Description

Represents the result of an inner solve.

Author: Mark Hoemmen

Warning: This is EXPERIMENTAL CODE. DO NOT RELY ON THIS CODE. The interface or implementation may change at any time.

An "inner solve" is an invocation of an iterative method, itself used as the operator or preconditioner for another iterative method. Inner solves may converge or not converge; they take some number of iterations to do either, and that number is less than or equal to some maximum number of iterations. The inner solve result may represent the result of solving for a single right-hand side, or it may aggregate the results of solving for multiple right-hand side(s).

Constructor & Destructor Documentation

Belos::InnerSolveResult::InnerSolveResult	(	const ReturnType	theResult,
		const int	theNumRestartCycles,
		const int	theTotalNumIters,
		const std::map< std::string, double > &	theExtraData
	)

Constructor.

Parameters

theResult	[in] Result of the solve, in numerical terms (Converged or Unconverged)
theNumRestartCycles	[in] Number of restart cycles started (not necessarily completed, if convergence happened before the end of the restart cycle). Zero means the initial guess was accurate enough to be judged Converged.
theTotalNumIters	[in] Total number of iterations, summed over all restart cycles.
theExtraData	[in] Any more data that the inner solve implementation would like to expose to the outside world. The data are stored as a map from the string label, to a double-precision floating-point value.

ReturnType Belos::InnerSolveResult::result ( )

inline

Did the inner solve converge?

The ReturnType enum currently only has two values: Converged and Unconverged. This may or may not change in the future, which is why we express convergence using ReturnType rather than a Boolean value.

Definition at line 69 of file BelosInnerSolveResult.hpp.

int Belos::InnerSolveResult::totalNumIters ( ) const

inline

Total number of iterations completed over all restarts.

This is the sum of all iterations over all restarts.

Definition at line 76 of file BelosInnerSolveResult.hpp.

int Belos::InnerSolveResult::numRestartCycles ( ) const

inline

Total number of restart cycles.

Definition at line 81 of file BelosInnerSolveResult.hpp.

const std::map<std::string, double>& Belos::InnerSolveResult::extraData ( ) const

inline

"Extra" data from the inner solve.

The inner solve may choose to expose more data to the outside world than just the data above. The data are stored as a map from the string label, to a double-precision floating-point value.
